Found in the five-node test, each with a check that failed first:
- A node with answers it could not give to two stuck senders began no
text at all. It now holds back only text from a sender whose own
answer is still with it.
- KILL waited to tell a stuck node, and a typed line that broke it left
the nodes after it untold. GONE is put with the messages waiting, as
how text ended is, and goes when it can.
- So that 'tell, then wait' still works, AWAIT does what (IDLE) does but
for beginning text: it looks through the messages waiting, offers what
is to be passed on and what is owed, and sleeps in the wait. A waiting
node no longer keeps back what passes through it.
- A node in the wait with an offer on a port that turns out to have
nothing on it is woken and told so (which port: 2 * V4_PORTS + k); no
error is raised on it. (GATE) makes it error 18; (IDLE) and AWAIT let
the message go. Before, removing a node raised 'No one on that port'
on the unrelated text of a neighbour that had something queued for it.
make -C v4 test and sanitize at both widths, hosted-check.
